The eroded headwall of the 1.5-km-wide 1902 crater extends from just below the summit down to 2.2 km elevation, where a volume of 0.5 km3 was removed during the eruption. The Santiaguito lava dome complex (left) began growing in the new crater in 1922. This 1991 view shows a lava flow descending the right flank of the dome.
